From HollywoodBowl.com:
We are sad to share that, for the first time in its almost century-long history, the Hollywood Bowl will be silent this summer. In response to the latest guidance of public health officials and in an effort to protect our artists, audiences, staff, and community from the spread of COVID-19, we are canceling the 2020 season at the Hollywood Bowl. This includes LA Phil-presented concerts scheduled from June 6 through September 26.
Ticketholders to canceled events can use the credit for a future LA Phil-produced concert at the Hollywood Bowl, Walt Disney Concert Hall, or The Ford; or request a refund. For assistance, please contact us by email at information@laphil.org, or by phone at 323 850 2000 between 10am and 6pm Monday through Friday. To avoid experiencing longer than normal wait times due to heavy phone volume, we encourage you to contact us by email.
The Hollywood Bowl is managed by the LA Phil, a non-profit organization supported by ticket sales and donations. The decision to cancel concerts is painful, as is the impact this crisis is having on our musicians, staff, and audiences. If you are able, please help us continue enriching lives through our music, YOLA and other learning and community programs by considering making a contribution to the LA Phil.
